Im getting a low to high pitch whine coming from my Supercharger as I accellerate and its getting worse. I have a 1998 Pontiac Grand Prix GTP. This started about a week ago and I just changed the coupler in the Snout and I used GM Supercharger Oil about the same time. I think it might be the Rotor bearings going bad but Im not sure. Any answer as to what this could be will be greatly appreciated. A friend of mine said that when I changed the oil I cleaned out what was keeping the bearings from failing, but the bearing problem would have showed up anyway. I have 137,000 miles on the engine and I keep the fluids top off and changed regularly. No leaks at all.
